<div dir="ltr">Hi Alexander,<br>sounds like a plan to me. I'll update to 2.2.2 over the weekend (on both machines) and we can take it from there. As for you pointers:<br><br>- The two UPSs were purchased at the same time (so I have no reason to believe their internal hardware is different).<br>
- Both computer are different (i.e. different motherboard etc.) so I don;t think it's a host hardware issue.<br>- They're both running Fedora 8 with the latest kernel, albeit that one is x86_64 and one is i386.<br>
<br>That said, I'll upgrade them over the weekend and take it from there. If you could let me know about any specific things you want me to take a note of and how to do stracing etc, I'll do so.<br><br>Cheers,<br>

</div>First of all I suggest you to update your NUT to the latest version. There is<br>
at least one reason for that - megatec_usb driver now supports automatic<br>
reconnection after link fail. This is not a fix.<br>
<br>
I have several suspects on this subject:<br>
<br>
1. hardware.<br>
<br>
Something could not ok in both UPSes (not very likely) or in the USB host<br>
hardware. Try connecting the UPSes to other machines.<br>
<br>
2. software<br>
<br>
It could be everything: kernel, udev, NUT... I think strace-ing megatec_usb<br>
can help.<br>
